Report reveals little new info on Boston bombing

Boston Marathon bombing suspect Dzhokhar Tsarnaev. In court documents filed Monday, March 17, 2014, prosecutors said Tsarnaev should not be allowed to see autopsy photos that will not be used at his trial. They said allowing the man accused of killing them to see photos of their mutilated bodies "would violate the victims' rights to dignity and privacy and subject them to needless harm and suffering."

A new congressional report on the federal investigation into the Boston Marathon bombings includes few previously unknown details of the case.

The report, released Wednesday, speculates without any evidence that bombing suspect Tamerlan Tsarnaev might have met with militants overseas months before the explosions and says it's reasonable to assume he was inspired by the activity and ideology of foreign terror groups.

It also acknowledges that the facts as known about his travel don't indicate any connection between the bombings and any outside terror network.

Much of the congressional report cites contemporaneous news articles for facts in the case, including those by The Associated Press.

Twin bombs placed near the finish line of last year's marathon killed three people and wounded more than 260.
